Microbial Desalination Cell

Microbial desalination cell (MDC) built on surface modification has been studied for seawater desalination. Herein, the bio-catalytic surface modification for maintenance the long-term MDC performance during desalination process has been developed. The goal of this study is to provide and develop a seawater desalination system without requiring energy support by applying a modification of anode as an electron acceptor, and the different potential charges that occur between anode and cathode can play as driving force for electrodialysis of seawater desalination. Yeast has been applied as biocatalyst, meanwhile neutral red has been chosen as redox mediator to facilitate the electron transport from bioactivity of cells. Several types of surface modification have been conducted, i.e. biocatalyst-mediator immobilization and electropolymerization of NR at the surface of the anode. The optimization of each device has been characterized by cyclic voltammetry, chronoamperometry, and observed in Microbial fuel cell (MFC) prior functioned in MDC. The concentrations of salt ion migration have been determined by Ion Exchange Chromatography.  MFC results reported that the best configuration of surface modification was obtained from CF/PNR then applied in MDC. CF/PNR delivered the highly significant performance by having the maximum value of all tested parameters, i.e 42.2% of current efficiency; 27.11% of bio-devices efficiency; 92.5 mA m-2 of current density and also 61% of NaCl transport. The profiles of surface devices have been detected by Scanning electron microscope (SEM) and Energy Dispersive X-ray spectroscopy (EDX). A several spherical shapes around 4 nm within alginate layer have been detected from SEM images and it was confirmed as yeast, meanwhile 5.04% of N has been found from EDX spectrum and was indicated from PNR. The results show that surface modification could be a promising method for bioelectricity generation which simultaneously produces electricity and seawater desalination and provides a green chemistry technology.

A new method is proposed and equipment is developed for applying a polyamide antifriction coating to worn surfaces of parts. Its use with a machine tool with NC implements the principle of additive technology. The composition of the polyamide composition was selected for the restoration of permanent joints, which ensure their protection against fretting corrosion and the required strength.

This paper describes a new method of die surface modification by ordinary Electrical Discharge Machining (EDM) tool. First, the principle of this method is studied. Secondly, the technology and characteristics of the die steel coating are discussed in detail based on lots of experiments, and the results show that the die steel characteristics are improved evidently by using EDM. At last, the technology is applied to the punch die initially, and it can be drawn that the life of the coated punch die is improved evidently compared with the non-coated punch die through the punching test.
